How many pieces of junk are orbiting Earth now?
It is estimated that there are over 9,000 tons of space debris currently in orbit around Earth, consisting of discarded rockets, defunct satellites, and fragments from collisions. These objects pose a risk to operational satellites and spacecraft in orbit. Multiple organizations are working on developing solutions to mitigate the issue of space debris.
Why is there junk in space?
The junk consists of the remains of the satellites that have been launched from Earth. They have outlived their usefulness and have been abandoned. Eventually their orbit decays and they fall back to Earth. Most will totally burn up due to friction in the atmosphere. Little of it will reach the surface. But it does pose a hazard to the launch of new satellites and spacecraft.
What are the artificial satellites of the Earth?
All the satellites, communications, exploratory, military etc. are artificial satellites of Earth.
How do left over materials in space pose a threat to people on the ground?
Leftover materials in space, such as defunct satellites or fragments from collisions, pose a threat to people on the ground because they can re-enter the Earth's atmosphere unpredictably and potentially cause damage or injury upon impact. There is a risk that these objects could land in populated areas, posing a danger to human life and property. Efforts are made to track and monitor space debris to mitigate this risk.
What are soler flares?
Solar flares are sudden bursts of energy on the sun's surface that release intense radiation across the electromagnetic spectrum. They can cause disruptions to communication systems on Earth and pose a risk to satellites and astronauts in space.

Does the earth have two satellites or Mars?
Mars has two natural satellites. Earth has one.
Where do communications satellites orbit?
Communication satellites orbit around the Earth.Communication satellites orbit around the Earth.Communication satellites orbit around the Earth.Communication satellites orbit around the Earth.
Do asteroids comets and meteoroids pose danger to earth?
Meteoroids generally do not pose much of a risk as they are generally small enough to burn up in the atmosphere, and do not reach the surface. Asteroids and comets are larger and can cause potentially catastrophic damage if they strike Earth.
What are natural and artificial satellites?
Natural satellites are organic objects that orbit the earth such as the moon. Artificial satellites are objects humans propel through the earth's atmosphere in order to orbit the earth such as satellites for TV and radio signals.
Which source of gravity is maintaining all four satellites around the earth?
Satellites of the Earth are held in their orbits by the Earth's gravity. That includes the Moon and all the artificial satellites etc. that are up there.
Why would you classify the moon and the earth as satellites?
